2012: Twenty-year-old gunman Adam Lanza fatally shoots 20 children and six adult staff members at Sandy Hook Elementary School in Newtown, Connecticut, and then commits suicide by shooting himself in the head. Before the shootings at the school, Lanza had shot and killed his mother at their home. The incident was the second deadliest mass shooting by a single gunman in American history, after the 2007 Virginia Tech shooting.
